To aZZ whom itf'may concern:

Be it known that I, SAM HARBISON, a citizen of the UnitedSt-ates,residing at Knoxville, in the count-yiof Knox and State of Tennessee,have inventeda new and useful Spring for Beds or the Like,'of which thefollowing is a specification.

nature, and also to so prepare the same that they may be directlyattached to bed or other 1 slats or strips and removablewith the latterin series and as readily replaceable in the same manner. j

The invention consists in the construction and arrangement .of'theseveral parts, which will be more fully hereinafter described andclaimed. 1

In the drawings, Figurel is a perspective view of a spring embodying thefeatures of the invention and shown applied to a holding device. Fig. 2is a similar view of a modified form of the spring, also shown appliedtofa holding device. the head portion of one of the springs, showing acap or button attachment therefor. v

Similar numerals of reference are employed to indicate correspondingparts in the several views.

The numeral 1 designates a horizontallydisposed head, which in thepresent instance is of circular form and which emanates frominwardly-inclined vertically-disposed coils 2 on opposite sides of adiametrical line drawn through the head, the said coils being below theplane of the latter, so as to avoid the formation of upwardly-extendingwearing projections and permit the head to present a substantially flatsupport. Extending forwardly under the plane of thehead atan'inclination and crossing the planes of each other are 'two stems 3,which continue from the lower portions of the coils 2 and merge intolower vertically-arranged substantially parallel coils 4, the stemsrunning into the outer portions of Fig. 3 is a sectional view of r thecoils 4 (shown by Fig. l) and into the inner portions of the coils 4(shown by Fig. 2.)

i The parts thus far set forth in both forms of springs are preciselysimilar in construction, and from the coils 4 substantially U- shapedholders 5 project horizontally in both instances to fit over and clampfirmly in engagement with slats or strips 6, as shown in dotted lines,the holders shown by Fig. 1 differing from those shown by Fig. 2 andextend from the inner portions of the coils 4 in parallel relation, thelower free terminal portions of the holders in this form of the devicehaving upwardly'directed studs 7, that fit into suitable openings in theslat orstrip 6. holders shown by Figs. 2 project horizontally from theouter portions of the coils 4 and .con-

verge toward vertical members 8, that are loosely tied by a band orother link 9 engaging the same, the holders in this instance from thelower portions of the said members 8 being struck down to form bends l0and then extend forward divergently in a horizontal plane tofrictionally bear against the under side of the slat or strip. The uppermembers of both forms of holders bear on the top surfaces of the slatsor strips to which they are applied,and the coils 4 are also similarlybraced and reinforced in their operation. Consequently a pressureexerted on the head 1 of either of the forms will be yieldinglyreceived, in view of the coils 2, from which said head and the stems 3will be depressed and ride over each other, the coils 2 and 4contracting during the depression of the stems, so that when thepressure on the head is relieved therefrom the parts will quickly andreliably resume their normal positions. It will be seen that the strainwill be taken up and absorbed by the coils 2 and 4 and that notransverse force will .be brought to bear on the stems, whichareshielded by the head above receiving all the weight-pressure.

It is proposed to construct the springs set forth of resilient wire ofsuitable gage having considerable tensile strength, and by cross-.

ing the stems, as stated, the pressure strain received through the head1 in either instance will be diverted and transmitted to the coils Y 4in lateral directions with obvious advantages, the inclination of thecoils Zaccommo- The dating the angular direction and crossed arrangementof the stems. These springs will be arranged at regular intervals alongthe length of the slat or strip and removable from a bed, furnituregenerally, or any cushion device in which the springs are usedsimultaneously with the removal of the slats or strips and similarlyreplaced in operative position. It is obvious that after the slats orstrips are disposed in position the springs may be tied in series, aswell understood in the art, though this mode of connection will not benecessary to obtain a successful operation of the same, and, in fact,itis preferred that they remain isolated, as shown.

To avoid injury to mattresses, upholstery, and the like, it is intendedto use a cap or button 11 in the head 1. Said cap or button has an upperflat surface 12, an overhanging flange 13, and a circumferential groove14 to form a seat for the head, as shown by Fig. 3. This device has notbeen shown applied in Figs. 1 and 2 to avoid hiding the parts of thesprings, and it is proposed to form the said cap or button of wood,pulp, paper, or any other material adapted for the purpose. By the useof this head-protector wear on the parts contacting therewith isavoided, and the spring is materially strengthened.

The preferred forms of spring have been shown; but it is obvious thatfor dilIerent uses changes in the size, proportions, and minor detailsmay be resorted to without departing from the spirit of the invention.

Having thus described the invention, what is claimed as new is- 1. Aspring having a horizontal head with stems extending downwardly underthe same at an angle of inclination and crossing each other, the saidstems merging into lower coils stem;

having horizontal substantially U shaped holders projecting therefrom toremovably clamp over the edge of a slat or strip.

2. A spring having a horizontal head with stems extending downwardlyunder the same at an angle of inclination and crossing each other, thesaid stems merging into lower coils having attaching members.

3. A spring having a horizontal head with inwardly-inclined coils at oneside of the center and beneath the same, stems extending from said coilsat an angle of inclination be; low the head and crossing each other andmerging into lower upright coils provided with attaching members.

4. A spring having a horizontal head with inwardly-inclined coils belowthe plane of the same, stems continuing from said coils at a downwardangle of inclination under the head and merging into vertically disposedcoils provided with attaching members, the stems being crossed,

5. The combination with a slat or strip having openings in the lowerportion thereof, of a spring having a horizontally-disposed open headwith stems extending downwardly under the same atan angle of inclinationand crossing each other, the said stems merging into lower upright coilsbearing upon the slat and having substantially U-shaped holders withlower members terminally projected upwardly to engage said openings, thesaid head being adapted to receive a cap.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

SAM HARBISON.
